Karl Malden was born as Mladen George Sekulovich, son of Minnie Sebera and Petar Sekulovich.

A FamilySearch record search turns up a marriage record for Petar Sekulovich and Minnie Sieberg, performed by Reverend S. Voyvodich, Rector of S.O.C. of Chicago. According to the 1910 census, his first name was "Sava".

It was indeed Father Sava Vojvodich (Voyvodich), who served at the church from 1908 to 1918. Karl wrote that his mother gave up her Catholicism when they married, and even her native language (Czech).

Minnie's maiden name was Sebera, but much of the family in America used "Seberg" (rendered in Minnie's marriage record as "Sieberg"). A clue for the extra credit question: "Minnie" was not her name at birth.

Minnie's first name is Zofia. The Ellis Island manifest for her arrival (Apr 16, 1907) shows she is traveling with her mother Genofeva (and siblings Marya & Adolf) . It indicates they are joining her father Halevly (? penmanship is hard to make out) in Chicago.

That's them. Karl wrote that "The Sebera family immigrated to this country in three waves: first, my mother's father with his eldest daughter; then her mother with three more children (including my own mother); and then the grandmother with the rest of the nine children." Here's a naturalization record for "Genevene" Sebera. She also went by "Jenny."

The family does appear in the 1910 census, but the spelling of the surname might make them hard to find.

Can anyone confirm her father's name, and perhaps even find her mother's maiden name?

Actually, 2 Chicago Tribune articles exist re: Valentine Sebera: 18 Aug 1910 concerning his family's immigration to the US, including his mother Marie, and Dec 1915 article concerning his death to a fall on the ice.

Yes! His name was Walenty, anglicized to Valentine. The family can be found in the 1910 census in Chicago under the name "Sewera."

Minnie's sister Elsie married John Sorich, 18 Jan. 1920 in Chicago, and died in California in 1989. Her death record reveals the maiden name of her mother—Agel. So, Karl's maternal grandparents were Walenty and Genovefa (Agel) Sebera.

I just found this Web page and I'm so excited I can hardly write! I have been researching my family genealogy. My maternal grandfather was Emanuel Agel (1881? - 1968), and relatives often said we were somehow related to Karl Malden. Emanuel came through Ellis Island on March 18, 1908, using the alias "Franz Podszewka". (He also later went under the alias "Emil Hager, Sr.") On the ship passenger record, he listed his USA contact as his "cousin, Valentin [Walenty] Sebera". Because of Emanuel Agel's use of several aliases, concrete information about him has been extremely hard to come by. Thank you for supplying several *crucial* pieces of the genealogical puzzle!

As a follow-up, I have just learned the names of Genovefa (Agel) Sebera's parents: Ignac Agel and Magdalena Zmijová (Zmija). So they would be great-grandparents of Karl Malden and uncle/aunt of my grandfather Emanuel Agel. I learned this because I also just discovered a Sebera family genealogical website in the Czech Republic!

I did a Google translation of the Czech, and on one of the pages, the author Ivo wondered whatever became of Walenty and Genovefa Sebera and their descendants after they emigrated to the USA! Boy, did I have some info to tell him! And the above info was what he emailed me in response. Thanks again!

I hope you don't mind one final follow-up regarding Karl Malden's ancestry and researching my relationship to him. Ivo Sebera in the Czech Republic has found genealogical documents indicating that my maternal grandfather, Emanuel Agel, and Genovefa (Agel) Sebera were in fact full brother and sister, children of Ignac Agel and Magdalena Zmijová (Zmija). That would make my mother and Minnie (Sebera) Sekulovich first cousins, and Karl Malden and me second cousins. Thanks again for your crucial help in solving a family mystery!
